java调用存储过程的方法

java调用存储过程时会使用到的方法

public void produceCallExecute(final String sql, final Object... params)
			throws SystemException {

		template.execute(new CallableStatementCreator() {

			public CallableStatement createCallableStatement(Connection con)
					throws SQLException {
				// TODO Auto-generated method stub
				CallableStatement call = con.prepareCall(sql);
				int index = 1;
				for (Object param : params) {
					call.setObject(index, param);
					index++;
				}
				return call;
			}
		}, new CallableStatementCallback<Object>() {

			public Object doInCallableStatement(CallableStatement cs)
					throws SQLException, DataAccessException {
				// TODO Auto-generated method stub
				cs.execute();
				return null;
			}
		});
	}
